This report presents a survey of track renewal machines and track renewal systems in Europe and North America. Topics covered include a brief history of track renewal, traditional North American selective track maintenance, and each of the major track renewal machine types currently in use. Emphasis is given to the Canron P-811-based system: p-811 operations are described in detail, including direct observations of the machines operating in Italy and on the Northeast Corridor. Also included are reviews of three recent studies of the economics of track renewal systems for U.S. railroads. The studies used different scenarios and therefore produced different results. However, each study did forecast a positive rate of return on the investment required for track renewal systems to replace selective maintenance methods. The report concludes with a brief account of each of the seven major issues that affect the economics of track renewal but that have yet to be studied in detail.
